Det-Sen Monastery
The Det-Sen Monastery was a place of Buddhist worship located in Tibet. The Doctor visited the monastery on several occasions.
In 1630, the Doctor helped the Det-Sen monks fend off bandit attacks and was entrusted with the monastery's holy Ghanta.
In 1735, Abbot Padmasambhava, under the influence of the Great Intelligence, began constructing robot Yeti.
In 1935, the Doctor returned to the Monastery in his second incarnation, bringing with him Jamie McCrimmon and Victoria Waterfield. They helped the monks and Professor Edward Travers defeat the Intelligence and the Yeti. (TV: The Abominable Snowmen)
